Everyone’s done it – deleted a Facebook message they meant to keep (sometimes the trigger-happy clicker finger can cause serious remorse.) People think they’ll never see their messages again. But this is not the case. That’s right, a time machine isn’t necessary to retrieve deleted messages. Facebook knows the accidental deletion of messages can happen and they’ve created an easy way for anyone with an account to go back and view everything they’ve done on their account.

In order to receive deleted messages in Facebook, you’ll first need to log-in to the Facebook account you want to retrieve messages from.

STEP 1 : Go to “Account Settings”

After you’re logged in, go to “Account Settings” in the top right corner of the window.

STEP 2: Once the “General Account Settings” page loads, click on “Download a copy of your Facebook data” at the bottom of the page.

Download Your Archive

STEP 3: After you click on the “Download a copy…” link, you’ll be brought to a page where you can download everything you’ve done on your Facebook account since the birth of your account. Click on the green button that says “Start My Archive.”

STEP 4: Request My Download,” will open, informing you it can take a while (typically 2-3 hours) to gather all of your information. Click “Start My Archive” again to launch the gathering process.

STEP 5: And that, you’ll be told to go to the email account associated with your Facebook profile where a download link to your archive will be sent. Again, it may take 2-3 hours to arrive. Once it does, click on the link in the email to download your archive.

STEP 6: And before you can download the archive, you will need to reenter your password.

STEP 7: Finally, click on “Download Archive” button that appears after entering your password. Your archive will download to your computer. Unzip it, then open the file named “index.”

The file containing your archived data will open and click on “Messages” and all of your past messages will load.

To easily find the message you’re looking for, search by keyword. Press “CTRL + F” or “F3” to access the keyword search process, and that’s it. Once you find the message, copy and paste the contents into a Word document to save.See: Facebook Logout All Devices
